KOS by reSAWN TIMBER co. features Kebony shou sugi ban specifically designed to create a beautifully CHARRED aesthetic. KOS can be used for exterior siding.

Kebony shou sugi ban exterior siding is a beautiful wood recommended by leading architects. It is sustainable, durable and requires no maintenance beyond normal cleaning. Kebony’s performance has been proven in a variety of applications including decking and cladding.

Developed in Norway, the Kebony® technology is an environmentally friendly, patented process, which enhances the properties of sustainable softwood with a bio-based liquid. The process permanently modifies the wood cell walls giving Kebony® premium hardwood characteristics and a rich brown color. After exposure to sun and rain the wood develops a natural silver-gray patina..

The Kebony® technology permanently transforms sustainable wood species such as pine into Kebony® wood with features that are comparable, and in some cases superior, to those of precious tropical hardwoods. This unique environmentally friendly process is also a superior alternative to traditional wood treatment based on impregnation with biocides (wood preservatives). The company’s patent-protected production processes yield products that deliver major improvements in durability and dimensional stability, at the same time as being highly attractive. The Kebony® products are suitable for a multitude of applications and designs – encompassing both indoor and outdoor applications.

KOS gives the Kebony shou sugi ban exterior siding a recognizable amount of texture and depth that combines with reSAWN’s award winning charred aesthetic to create a distinct and striking design.

Our charring & sealing process makes for beautifully designed exterior wood siding.  Like any exterior wood siding prefinished or finished in place, these materials will weather naturally over time and will require maintenance.  For interior applications, expect little to no change.  We’ve created this CHARRED USAGE GUIDE to tell you more.  

reSAWN’s CHARRED offering features Accoya, Kebony, cypress, cedar, black walnut, reclaimed hemlock and newly harvested western hemlock that is burnt in the Japanese tradition of shou sugi ban. Our award-winning CHARRED products pay homage to the traditional Japanese technique of “shou-sugi-ban” aka “yakisugi” without being literal.  Historically very specific in their definition, “shou-sugi-ban” and “yakisugi” have become common nomenclature for modern charred wood designs in general.  All of reSAWN’s CHARRED products are made in the USA, in our facility in Telford, PA.
